| 中文摘要: |
| 降低蒸汽消耗可以降低大豆油压榨企业的生产成本。以5 000 t/d大豆加工厂为例，从技术改造以及精细化管理方面介绍了降低蒸汽消耗的措施。技术改造措施包括将原浸出线的蒸汽喷射泵改为液环式真空泵、层碟式汽提塔改为筛板式汽提塔、浸出器沥干段栅格板间隙从0.4 mm增加为1.2 mm，对DC蒸脱机首层排放的废气、汽提塔二次蒸汽以及蒸汽凝结水的热量进行回收利用。精细化管理措施包括加强设备精细化控制、完善必需的计量设备、强化员工操作控制水平及KPI绩效考核管理。通过以上措施，可节省蒸汽约45 kg/t（以原料计）。 |
| 英文摘要: |
| Reducing steam consumption can reduce the production cost of soybean oil crushing enterprises. Taking a 5 000 t/d soybean processing plant as an example, measures to reduce steam consumption were introduced in terms of technological transformation and refined management. Technical transformation measures included changing the steam jet pump of the original leaching line to a liquid ring vacuum pump, changing the layer disc stripper to a sieve-plate stripper, and changing the grid plate gap in the drain section of the extractor from 0.4 mm to 1.2 mm, and recycling the spent gas discharged from the first layer of the DC evaporator, the secondary steam discharged from the stripper and the heat of the steam condensate. Refined management measures included strengthening refined control of equipment, perfecting necessary measuring equipment, strengthening staff operation control level and KPI performance appraisal management. Through the above measures, about 45 kg/t of steam (based on raw materials) could be saved. |
